Google Test: how to EXPECT_EQ non printable ASCII values

In my test I set an EXPECT_EQ() on a char against some characters like 'a', 'b' etc... so far so good.

Now I should test against a non printable ASCII character (0xFE). My character is defined as 'char' so a direct test against 0xFE will fail

char a;
a = 0xFE;
EXPECT_EQ(a, 0xFE);   <-- fail!!!
